Thailand operates a progressive tax system that is generally considered moderate by Southeast Asian standards. Chiang Mai follows the same tax structure as the rest of Thailand, with no city-specific variations. The system is based on both residence and source principles, meaning residents are taxed on worldwide income while non-residents are taxed only on Thailand-sourced income. Thailand's tax system can be favorable for expatriates due to relatively low effective tax rates, generous personal allowances, and special incentives for certain professionals and investors. The country has been actively modernizing its tax administration, with increasing digitalization of filing procedures.
